Predicting which patients will respond to a given treatment option would support personalized treatments and improve the efficiency of healthcare systems. Although previous neuroimaging studies have examined possible pre-treatment predictors of response to treatment, the findings have been somewhat inconsistent, and no other study has examined habituation to stimuli as a predictor. In this study, 16 treatment-seeking adults (M<jats:sub>Age<\/jats:sub> = 43.63, <jats:italic>n<\/jats:italic> = 10 women) with a primary diagnosis of PTSD passively viewed pictures of emotional facial expressions during functional magnetic resonance imaging (fMRI). After scanning, participants rated facial expressions on both valence and arousal. Participants then completed eight weekly sessions of prolonged exposure (PE) therapy. PTSD symptom severity was measured before and after treatment. Overall, participants showed symptomatic improvement with PE. Consistent with hypotheses, lesser activation in the amygdala and greater activation in the ventromedial prefrontal cortex during the presentation of fearful vs. happy facial expressions, as well as a greater decline in amygdala activation across blocks of fearful facial expressions at baseline, were associated with greater reduction of PTSD symptoms. Given that the repeated presentation of emotional material underlies PE, changes in brain responses with repeated stimulus presentations warrant further studies as potential predictors of response to exposure therapies.<\/jats:p>","DOI":"10.3389\/fnbeh.2023.1198244","type":"journal-article","created":{"date-parts":[[2023,7,10]],"date-time":"2023-07-10T05:44:47Z","timestamp":1688967887000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Pre-treatment amygdala activation and habituation predict symptom change in post-traumatic stress disorder"],"prefix":"10.3389","volume":"17","author":[{"given":"Cecilia A.","family":"Hinojosa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael B.","family":"VanElzakker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Navneet","family":"Kaur","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia M.","family":"Felicione","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meredith E.","family":"Charney","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Bui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luana","family":"Marques","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Summergrad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott L.","family":"Rauch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi M.","family":"Simon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa M.","family":"Shin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,7,10]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"48","DOI":"10.1016\/j.pscychresns.2013.05.001","article-title":"Neural responses during emotional processing before and after cognitive trauma therapy for battered women","volume":"214","author":"Aupperle","year":"2013","journal-title":"Psychiatry Res."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1254","DOI":"10.1038\/npp.2013.328","article-title":"Single-subject anxiety treatment outcome prediction using functional neuroimaging","volume":"39","author":"Ball","year":"2014","journal-title":"Neuropsychopharmacology"},{"key":"B3","doi-asserted-by":"publisher","first-page":"214","DOI":"10.1176\/appi.ajp.162.2.214","article-title":"A multidimensional meta-analysis of psychotherapy for PTSD","volume":"162","author":"Bradley","year":"2005","journal-title":"Am.
